Not the parent, but I once inherited a bunch of tools that used the same tracing function. Akin to dtrace. 6 people wrote 6 tools over different domains all with their own post-processing, filtering, formatting, etc...

It was a support nightmare, so we built a common library and collapsed the code base by 70%. Each tool was probably in the -8k eslocs range. Thankfully it wasnt c++.
